The method can also comprise determining, by the device, that a beam failure of a beam pair link between the base station device transmitter antenna and a receiver antenna has occurred in response to the reference signal being determined not to satisfy the predefined criterion related to signal quality.

In another embodiment machine-readable storage medium, comprising executable instructions that, when executed by a processor of a device, facilitate performance of operations.

FIG. 1 illustrates an example wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can comprise one or more user equipment UEs 104 and 102, which can have one or more antenna panels having vertical and horizontal elements. A UE 102 can be a mobile device such as a cellular phone, a smartphone, a tablet computer, a wearable device, a virtual reality (VR) device, a heads-up display (HUD) device, a smart car, a machine-type communication (MTC) device, and the like. UE 102 can also refer to any type of wireless device that communicates with a radio network node in a cellular or mobile communication system. Examples of UE 102 are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles etc. User equipment UE 102 can also comprise IOT devices that communicate wirelessly. In various embodiments, system 100 is or comprises a wireless communication network serviced by one or more wireless communication network providers. In example embodiments, a UE 102 can be communicatively coupled to the wireless communication network via a network node 106.

The non-limiting term network node (or radio network node) is used herein to refer to any type of network node serving a UE 102 and UE 104 and/or connected to other network node, network element, or another network node from which the UE 102 or 104 can receive a radio signal. Network nodes can also have multiple antennas for performing various transmission operations (e.g., MIMO operations). A network node can have a cabinet and other protected enclosures, an antenna mast, and actual antennas. Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. Examples of network nodes (e.g., network node 106) can comprise but are not limited to: NodeB devices, base station (BS) devices, access point (AP) devices, and radio access network (RAN) devices. The network node 106 can also comprise multi-standard radio (MSR) radio node devices, including but not limited to: an MSR BS, an eNode B, a network controller, a radio network controller (RNC), a base station controller (BSC), a relay, a donor node controlling relay, a base transceiver station (BTS), a transmission point, a transmission node, an RRU, an RRH, nodes in distributed antenna system (DAS), and the like. In 5G terminology, the node 106 can be referred to as a gNodeB device.

Wireless communication system 100 can employ various cellular technologies and modulation schemes to facilitate wireless radio communications between devices (e.g., the UE 102 and 104 and the network node 106). For example, system 100 can operate in accordance with a UMTS, long term evolution (LTE), high speed packet access (HSPA), code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), OFDM, (DFT)-spread OFDM or SC-FDMA)), FBMC, ZT DFT-s-OFDM, GFDM, UFMC, UW DFT-Spread-OFDM, UW-OFDM, CP-OFDM, resource-block-filtered OFDM, and UFMC. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and 104 and the network device 106) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.).

In various embodiments, system 100 can be configured to provide and employ 5G wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, Internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs).

In an embodiment, UE 102 or 104 can determine when a beam failure of a beam pair link has occurred and determine whether to initiate a beam recovery process based on the importance of the beam pair link, or based on the amount of downlink control information or uplink control information being passed by the beam pair link. Temporary interference cause by blockage (due to the millimeter wave wavelengths of the transmission medium) can render one or more beam pair links (transmission streams from an antenna on a transmitter to a antenna on a receiver) of MIMO transmission disabled. This can prevent the decoding of the blind decoding candidates in the transmission and require retransmission. If only a small amount of downlink control information is missing however, the transmission process can proceed, without retransmission of the missing downlink control information. Therefore, by taking into consideration the importance of the control resource set (the set of blind decoding candidates in the transmission carrying the downlink control information) unnecessary beam recovery procedures can be avoided.

Turning now to FIG. 2, illustrated is an example block diagram showing a message sequence chart 200 in accordance with various aspects and embodiments of the subject disclosure.

In an embodiment, a gNodeB (or other network node) 202 can issue a reference signal 206 that can be received by a UE 204. The reference signal can be beamformed in some embodiments, or non beamformed in other embodiments.

Based on the reference signal 106, the UE 104 can measure the channel response, and determine channel state information (CSI) to give as feedback to the gNodeB 202. The channel state information can also provide an indication of the reference signal quality at 208 and can include a channel quality indicator, precoding matrix index, or advanced PMI. This channel state information can refer to the known channel properties of the communication link between the gNodeB 202 and the UE 204. The channel properties can reflect how the signal propagates from the transmitter to the receiver and represents the combined effect of, for example, scattering, fading, and power decay with distance.

Based, on channel state information, the gNodeB 202 can then send downlink control information (DCI) 210 to the UE 204 which enables the UE to receive data over a data traffic channel, or uplink control information which can facilitate configuring the UE 204 to send data back to the gNodeB 202. The downlink link control information and/or uplink control information can be encoded in one or more radio resource elements in a transmission. The physical resource elements can correspond to one subcarrier and/or one OFDM symbol. The UE 204 can perform blind decoding of a set of PDCCH candidates that may contain the DCI 110. The number of candidates blindly decoded can be based on the search space and/or aggregation level of the channel. In an embodiment, each beam pair link can transmit a control resource set (group of blind decoding candidates). The control resource sets can have varying numbers of blind decoding candidates at different aggregation levels (the number of physical spaces or radio resource elements that DCI information can be mapped to). Higher aggregation levels mean that the same amount of DCI is mapped to more locations, which increases the robustness of the transmission.

The relative importance of the beam pair link can be determined at 212 based on the control resource set the beam pair link is associated with. A control resource set is a set of resource elements where each UE attempts to blindly decode the downlink control information. A user can have one or more control resource sets. Each control resource set can be associated with a search space, and the search space can include aggregation level(s) and number of decoding candidates for each aggregation level.

In an embodiment, UE 204 can be configured with multiple control resource sets. Each control resource set is associated with certain number of blind decoding candidates. (The number of blind decoding candidates may be implicitly decided by the size of control resource sets in terms of resource elements A resource element can be the smallest modulation structure, or data unit. Each control resource set is associated with a set of beam pair links where each beam pair link includes a transmitter beam and a receiver beam. Each set of beam pair links is associated with a reference signal resource which is used to estimate the quality of the set of beam pair link.

In an embodiment, a beam failure event can be defined as “more than N effective blind decoding candidates failed” and the value of N is configured by network depending on local conditions. When the reference signal resource (maybe CSI-RS or SS-block) corresponding to a control resource set failed, all the blind decoding candidates associated with the control resource set are also considered to have failed. In some embodiments, a beam failure event can be based on the aggregation level of the control resource set. For instance, a beam failure event can be defined as “more than N effective blind decoding candidates with a certain aggregation level that have failed”.

After determining that the beam failure event has occurred, the UE 204 can request a beam recovery at 214, and at 216, the gNodeb 202 can initiate a new beam pair link using a different set of antennas.

As an example, UE 204 can be configured with 2 control resource sets (of downlink control information). Control resource set 1 associated with a first beam pair link has 12 blind decoding candidates and control resource set 2 has 2 blind decoding candidates. So, if the set of beam pair links associated with control resource set 1 failed (according to the measurement associated RS resource), the total number of failed blind decoding candidates is 12. If the reference signal associated with control resource set 2 failed or is below a predetermined signal strength or signal to noise ratio, the total number of failed blind decoding candidates is 2. If the network has as a threshold of 4 blind decoding candidates failed to declare a beam failure, then the failure of the first beam pair link would trigger the failure, but the failure of beam pair link 2 (associated with control resource set 2) would not trigger the failure.

In an embodiment when considering the aggregation level. if UE 204 can be configured with 2 control resource sets. Control resource set 1 has 12 blind decoding candidates, where 6 of the blind decoding aggregates are at aggregation level 2 and another 6 blind decoding candidates are at aggregation 4. While control resource set 2 has 2 blind decoding candidates at aggregation 4. And the failed blind decoding candidate is configured as aggregation 4 only. So if control resource set 2 failed, then the total number of failed blind decoding candidate would be 2 while if control resource set 1 failed, the total number of blind decoding candidates would be 6 which would trigger a failure event.

Turning now to FIG. 3, illustrated is an example block diagram 300 of a new beam pair link from the same network node in accordance with various aspects and embodiments of the subject disclosure.

In an embodiment, a beam pair link 308 between network node 306 and UE 304 can be blocked by object 302 (in the shape of a person, but could be any object capable of attenuating a millimeter wave transmission between the network node 306 and UE 304). After determining that the reference signal associated with the beam pair link 308 is below a threshold signal quality (e.g., as measured by signal strength, signal to interference plus noise ratio, etc.), and after determining that the control resource set associated with the beam pair link 308 is of enough significance or importance, or comprises a predetermined number of blind decoding candidates at a certain aggregation level, the UE 304 can determine that the beam pair link 308 has experienced a failure event, and will send a request for beam recovery to the network node 306. A new beam pair link 310 can be formed to retransmit the downlink control information.

Turning now to FIG. 4, illustrated is an example block diagram of a new beam pair link from a different network node in accordance with various aspects and embodiments of the subject disclosure.

In an embodiment, a beam pair link 408 between network node 406 and UE 404 can be blocked by object 402 (in the shape of a person, but could be any object capable of attenuating a millimeter wave transmission between the network node 406 and UE 404). After determining that the reference signal associated with the beam pair link 408 is below a threshold signal quality (e.g., as measured by signal strength, signal to interference plus noise ratio, etc.), and after determining that the control resource set associated with the beam pair link 408 is of enough significance or importance, or comprises a predetermined number of blind decoding candidates at a certain aggregation level, the UE 404 can determine that the beam pair link 408 has experienced a failure event, and will send a request for beam recovery. The request can either be sent back to network node 406 or network node 412 and the new beam pair link to the network node 306. A new beam pair link 410 between network node 412 and UE 404 can be formed to retransmit the downlink control information.

The UE 404, network node 406, or mobile network can determine to introduce another network node (e.g., network node 412) if there are no suitable antenna pairs on network node 406 and UE 404 to establish a new beam pair link. This can occur of the object 402 is causing a significant enough blockage to interfere with the antennas of the network node 406.

Turning now to FIG. 5, illustrated is an example table showing aggregation levels for blind decoding in accordance with various aspects and embodiments of the subject disclosure

There can be different types 502 of aggregation levels 504, where each aggregation level 504 has a different size 506 and number of PDCCH candidate 508. The size 506 is derived by multiplying the number 508 of PDCCH candidates by the aggregation level 504.

For UE specific search spaces, there can be four aggregation levels, 1, 2, 4, and 8, with separate sizes and candidates per aggregation level. Each of the different aggregation levels can have different priority lists to facilitate the early termination of blind decoding by the UE when it receives the transmission from the base station device.

In various embodiments, the aggregation level can be configured by the base station device or the network for the UE based on a variety of factors, including the link quality of the UE and other quality of service concerns. For instance, a UE that is on a cell edge can use an aggregation level that is higher, such as level 8 since the number of PDCCH candidates are smaller, which can facilitate a lower code rate.

By taking into consideration the aggregation level of the control resource set, the importance of the beam pair link can be determined in another way. There are different aggregation levels that a PDCCH has (aggregation level is defined as the number of control channel elements aggregated for transmission for each PDCCH). There can be 4 possible aggregation levels (1, 2, 4, or 8). The higher the aggregation level, means the more likely that the UE will decode the DCI, as it occupies more CCEs, hence more bits, and uses a more robust coding. So for example channels that carry system information have a higher aggregation level.

Turning now to FIG. 6, illustrated an example block diagram 600 of a user equipment device 602 in accordance with various aspects and embodiments of the subject disclosure.

User equipment device 602 can include a reference signal component 604 that receives the reference signal and determines whether the reference signal quality is below a predetermined threshold, or the signal to noise ratio is below a threshold. The reference signal component 604 can determine that a reference signal associated with a beam pair link is below a first value determined by a predefined criterion associated with a strength of the reference signal, wherein the beam pair link is a transmission stream between a transmitter antenna and a receiver antenna.

An analysis component 606 can be provided to determine an importance of the beam pair link associated with the reference signal. The relative importance of the beam pair link can be determined by the analysis component 606 based on the control resource set the beam pair link is associated with. A control resource set is a set of resource elements where each UE attempts to blindly decode the downlink control information. A user can have one or more control resource sets. Each control resource set can be associated with a search space, and the search space can include aggregation level(s) and number of decoding candidates for each aggregation level.

In an embodiment, user equipment device 602 can be configured with multiple control resource sets. Each control resource set is associated with certain number of blind decoding candidates. (The number of blind decoding candidates may be implicitly decided by the size of control resource sets in terms of resource elements A resource element can be the smallest modulation structure, or data unit. Each control resource set is associated with a set of beam pair links where each beam pair link includes a transmitter beam and a receiver beam. Each set of beam pair links is associated with a reference signal resource which is used to estimate the quality of the set of beam pair link.

In an embodiment, a beam failure event can be defined as “more than N effective blind decoding candidates failed” and the value of N is configured by network depending on local conditions. When the reference signal resource (maybe CSI-RS or SS-block) corresponding to a control resource set failed, all the blind decoding candidates associated with the control resource set are also considered to have failed. In some embodiments, a beam failure event can be based on the aggregation level of the control resource set. For instance, a beam failure event can be defined as “more than N effective blind decoding candidates with a certain aggregation level that have failed”.

In response to determining that a beam failure event has occurred, the user equipment device 602 will initiate the beam failure protocol in which the recovery component initiates a transmission of a beam recovery request to a base station device associated with the transmitter antenna or another base station device. In response to sending the beam recovery request, the base station can initiate a new beam pair link and retransmit the downlink or uplink control information that was in the failed transmission.
